The younger Coral-Caste survivor, a sharp-faced man named Kest, thrust his brass blade forward, its tip glinting inches from Batzal’s sternum. Rejja, older and heavier, circled to Batzal’s left, his own dagger a dull crescent. Yutika, still near the prone form of Nim-Rua, flinched but did not move, her face a mask of calculated indifference. The cramped space felt smaller, choked by the smell of hot brass and desperation. “We’ve done the math, Engineer,” Kest hissed, his voice surprisingly steady. “Two mouths, two bodies that contribute nothing. This vessel can’t take it.” Batzal’s gaze flickered to Nim-Rua, then back to Kest. “And your figures are based on what? The thickness of your silk robes?” His voice was low, laced with the contempt of a man who knew the true arithmetic of survival. “I designed this hull. I know every joint, every plank, every stress point. You know only how to consume.” “Enough,” Rejja grunted, pushing his blade closer. “The maps. You need them. But you won’t survive to use them, not with that… burden.” He gestured with his chin towards Nim-Rua, then at Batzal, his eyes colder than the deep mountain springs of Mokhara. “The maps are already etched into my mind,” Batzal said, a faint smile playing on his lips. “And into my own schematics. Did you truly think I would rely solely on a Coral-Caste’s promises?” He paused, letting the implication sink in. “No. Your usefulness, like your wealth, is finite.” Kest’s eyes narrowed. “You bluff. Without the physical charts, you’re blind.” “Am I?” Batzal asked, his gaze drifting to a section of the curved wall, a barely visible seam running vertically between two massive cork-wood panels. It was a detail only an architect would recognize, a subtle articulation in the framework, designed to compartmentalize during maintenance or for isolation. He had built in a dozen such redundancies, secret passages, and hidden mechanisms born of sheer paranoia, safeguards against the very arrogance now facing him. “We’re taking control,” Rejja declared, stepping forward. “You and the weaver go over. It’s for the good of the rest of us.” “The rest of you?” Batzal’s smile broadened, a chilling, vindictive curve. “There will be no ‘rest of you’ if this ziggurat fails. And it will fail, under your ineptitude.” His eyes, usually detached, now held a glint of genuine menace. “You forget, gentlemen, I am not just the pilot. I am the architect. And architects build contingencies.” With a sudden, explosive movement, Batzal lunged not at either man, but towards the curved wall. His hand shot out, not to deflect a blade, but to a small, brass-filigree release lever cunningly hidden behind a decorative relief of a cascading spice vine. It was a detail so specific, so seemingly innocuous, that only its creator would know its function. His fingers, calloused from years of drafting and building, closed around it. He pulled. With a groan of stressed cork-wood and the harsh scrape of metal on metal, a section of the floor beneath Rejja and Kest’s feet began to retract. Not a trapdoor, but a clever, interlocking panel system that revealed a yawning vertical shaft. At the same time, massive, pressure-sealed panels slammed shut above them, plunging their compartment into an oppressive, lamp-less darkness. The entire upper tier, where the elites had huddled, was now severed from the lower hold. “What in the…?” Kest’s panicked cry echoed as he stumbled, scrambling to avoid the widening gap. Rejja, slower, swore loudly as the floor continued to recede. Their shouts quickly became muffled, indistinct, swallowed by the thick cork-wood and brass, the sounds of their frantic attempts to reverse the mechanism fading into the distant thrum of the engine. The separation was complete. Batzal stood panting, his back to the now solid, albeit scarred, wall that had once been the entry to the upper tiers. The interior space around him was smaller now, more confined, but the immediate threat was gone. He was alone in the lower hull, save for Yutika, who had watched the entire maneuver with wide, disbelieving eyes, and Nim-Rua, still unconscious. He knelt beside Nim-Rua, the stench of roasted flesh rising from her burns. He pulled a clean, tightly woven linen cloth from a supply locker and dipped it into their carefully rationed freshwater. He dabbed gently at the raw, blistered skin, trying to soothe the agony he knew she must feel, even in her stupor. Nim-Rua stirred, a low moan escaping her lips. Her eyes fluttered open, unfocused at first, then locked onto Batzal’s face. She tried to speak, a dry rasp. “Batzal… the numbers.” He shushed her, continuing to clean the wound. “Don’t speak. Save your strength.” But she persisted, her voice barely a whisper. “The ledger… it’s right. My weight… it’s too much.” She coughed, a wet, rattling sound. “You… you must… jettison.” Her eyes, clouded with pain, held a startling clarity, a raw acceptance of her own calculated demise. Batzal’s hands paused. He looked at her, truly looked, seeing not just a burden, not just a line on a chalkboard, but the woman who had helped him seal the hull, who had saved Yutika, who had shown him a kindness he rarely afforded himself. The vindictive satisfaction he had felt just moments before curdled into something bitter and cold. He had made a choice, sacrificing rations for her, and now she was offering herself up for his numbers. Before he could respond, a new sound cut through the oppressive silence: a sharp *CRACK*. It came from above, from the sealed-off upper tiers. Then another, louder, followed by a rhythmic thudding, the unmistakable sound of heavy implements striking wood. The buoyant vessel, built to withstand the boiling tide, groaned with a new, internal torment. Batzal’s head snapped up. He looked toward the ceiling timbers in sudden dread. The trapped elites, cut off from the engine room, from his navigation, from any hope of rescue, were not merely pounding on the walls. They were dismantling them. They were tearing apart the very structural components of the ziggurat, stripping the interior cork-wood. They were building a raft. And in doing so, they were signing the death warrants for everyone still inside, including themselves.
